It fetches the component record, creates an element (`$(componentType, { uri })`), and calls [`@inlay/render`](../packages/@inlay/render) in a loop until everything bottoms out in primitives. Each primitive maps to a custom HTML element (`org-atsui-stack`, `org-atsui-text`, etc.) styled by two CSS files. 19 19 20 20 - The response is streamed with Hono's `renderToReadableStream`.
